    Routing to Vias

    Yes everything green means its on one(Top) layer. Have not shown any underlying layers. So, basically the question was whether it is good practice to connect Diode Copper pad to surrounding Copper as shown in the picture i posted today OR the first picture from yesterday is better choice...

    Routing to Vias

    Sorry the below picture should actually be like this: When i deleted the traces to vias, it somehow was not updated.

    Routing to Vias

    Hi I have a Power connection passing from Diode to Surrounding Vias and into underlying Power Plane. Current through this Power Connection would be maximum 2-3A. Just wondering if routing the copper lines directly from Diode to only 3 vias is a good practice? There is Copper plane surrounding...

    Ground Pad Soldering Issue

    Hi Have encountered this issue over and over again that it is quite difficult to Solder a Wire or Connector to Through Hole Ground Pin with orthogonal connection to the Surrounding Copper(Ground) Plane as shown here: Top Layer connection is 0.2mm wide and Bottom Layer Connection is 0.4mm...

    Mating receptable for DF11-4DP-2DSA

    Hi I have a module which is using Hirose DF11-4DP-2DSA (Page 10)Straight Pin Header. I want to mate it with a 4-Pin Through Hole Receptable(don't have space for SMT Type) but Hirose does not offer DF11-4DS-2DSA. It means they don't have any receptable below 6 pins. I tried using SQT-102-01-L-D...

    Ground Pad Soldering Issue

    Hi I encountered a soldering problem while soldering 2 wires to my PCB. The hole on the top is for GND and the below one is for Power. The wire is not getting properly soldered in the Ground Hole, while not much of a problem on the Power Hole. The heat from the ground hole is getting spread...

    RS-422 D-Sub 9 pin Male Pinout

    Hi I am trying to figure out what could be the possible pinouts for the rest of the pins on a D-Sub 9 Pin Male Connector. I have only 5 pins necessary for RS-422 Communication as shown here: But can't figure out the rest of the 4 pins(1,4,6 and 9) should go namely: CTS+, CTS-, RTS+ and RTS-. I...

    Analog Input/Output Connections Wiring

    DO is not Digital Signal. It stands for Dissolved Oxygen. So, everything here is in Analog Domain.

    Analog Input/Output Connections Wiring

    Unfortunately I have very little information. When it comes to Cable Pinouts, i could find out that these Analog_In_2 and Analog_In_1 signals were going to these AD8628 Op-amps: The outputs from these Op-amps was connected to a 16:1 Multiplexer.
